APPENDIX. ()Q5 



It may be observed, that the late intense cold had 

 chapped my hands to a painful degree, and I had 

 greased them a few hours previous to observing the 

 needle. 



February 9th. — At 10 h 20 m p.m. the sky was 

 almost entirely covered with coruscations ; but the most 

 conspicuous was a broad serpentine and bright arch 

 extending from E.b.N. to W. b. S., and along which 

 there appeared at times to be two currents in active 

 motion from opposite points. 



I found the needle vibrating steadily as follows : — 

 0° 20' E., motion of aurora from W. to E. : 0° 05' E., 

 motion W. : 0° 20' W., undulating motion W. : 0° 05' 

 W., 00° 00', motion W. to E. across the zenith : 

 0° 20' E., a bright arch at E., 10° broad: 0° 10' E., 

 slight motion over the zenith, then the motion was from 

 W. to the zenith, 00° 00' : serpentine motion across 

 zenith from W. to E., 0° 40' E., 0° 30' E. : motion 

 over zenith, 0° 10' E. : motion from W. to E., not beyond 

 zenith, 00° 00'. The broad arch now moved southerly, 

 at an angle of 80°, and at the same time there was a 

 bright mass at S. E., 0° 20 E. : flashes flitting suddenly 

 between S.E. and E., 0° 10' E., 1° 20' E. 



Motion over zenith from W. to E., 0° 20' E. to 

 1° 00' E, generally diffused and very active: an un- 

 dulating mass at N.E., 2° 30' to 0° 20' E. : bright 

 mass at S.E., 0° 40' E. to 0° 20 E. : generally diffused 

 but still bright at S.E., 0° 10' W. : beams at W., 

 0° 25' W. : beams at N. E., 00° 00' : serpentine waving 

 across zenith from W. to E., in an arch, 00° 00' to 

 0° 25' E. : 00° 00', mass westward. 



Mass at W., extending easterly, with a rapid motion 

 from W. to E., 1° 00' E., to 0° 30' E., 1° 10' E., to 

 0° 35' E. : a bright mass at E., 1° 20 E. : motion AV,
